The Monte Santo Alkaline Intrusive Suite (MSAIS) is an association syenite foid, nepheline syenite and syenite, which are intruded in metapelites of the Rio do Coco meta-volcanic-sedimentary Sequence, presenting abundant pegmathoid veins cutting all of them. The ages obtained by Shrimp (1051 ± 22 Ma, 1048 ± 11 Ma) are very close those younger age obtained by U-Pb laser ablation (1056 ± 21), beeing interpreted as crystallization age. These dating reveal also that MSAIS rocks were affected by common succession of younger events below 550 Ma ago, responsible by the later rocky bodies of varying composition occurring in the region, including the alkaline pegmatites hosted in the nepheline syenite of the MSAIS.

The Monte Santo Alkaline Intrusive Suite (MSAIS) is an association syenite foid, nepheline syenite and syenite. The MSAIS rocks are intruded in metapelites of the Rio do Coco meta-volcanic-sedi- mentary Sequence and are abundant pegmathoid veins cutting all of them. The mineral paragenesis is represented by aegirina, arfvedsonite, albite and nepheline, crystallized during the initial phase of crystallization. A late magmatic phase show nepheline, perthite, calcite and biotite, and a hydrothermal phase allowed for the formation of cancrinite, sodalite, analcime and natrolita associated with altered nepheline. The geochemical analyses showed metaluminous and medium to high potassium characteristics, being classified as miaskitic rocks, according to agpaicity and the Na + K > 1/6Si indexes. However, the mineralogical assemblage suggests a low to medium agpaitic composition, which can be related to a transition from miaskitic to agpaitic crystallization regime. The rare earth elements showed depletion in heavy rare earth and a strong negative Eu anomaly and enrichments in the some lithophile elements, suggesting a differentiated pattern later, which can be associated to metasomatic alterations.

Cr(Ⅵ)是土壤和水体中常见的有毒污染物,将Cr(Ⅵ )转化为毒性较低的Cr(Ⅲ)是常用而有效的治理方法.本文采用褐铁矿对水中Cr(Ⅵ )进行处理研究,考察了褐铁矿投加量、Cr(Ⅵ)初始浓度、pH值、反应温度、铁矿石粒径大小以及添加不同物质等因素对褐铁矿去除效果的影响.结果表明,褐铁矿对Cr(Ⅵ)有很好的还原去除效果,Cr(Ⅵ)去除效率随褐铁矿用量的增加而增大,随Cr(Ⅵ )初始浓度的增加而减小,pH值越低越有利于反应的进行.铁矿石颗粒的直径越小,比表面积越大,也对反应越有利,而温度对Cr(Ⅵ)的去除影响不大.100目的褐铁矿颗粒去除Cr(Ⅵ )的能力为7.77mgCr(VI)/g.使用褐铁矿不仅可以将Cr(Ⅵ)还原为Cr(Ⅲ),还能将Cr(Ⅵ )彻底从水中去除.

The objective of this study was to evaluate the efficiency of Moroccan Bt strains against neonate larvae, third instar larvae and emerged adults of Ceratitis capitata. This Mediterranean fruit fly causes serious damages to Argan forest and other agricultural plants. There is no successful control program of this pest fly in the endemic Argan forest in Morocco. A single-dose test was performed on neonate larvae (25 μL/g) and adult (333.33 μL/g), when three doses of Bt toxins (50 μL/g, 100 μL/g and 150 μL/g) were tested against third instar of C. capitata. Among the twenty-six Bt strains examined, local Bt13.4 and Bt A7 strains showed highest toxicity levels against larvae and adults, when compared to the reference strain, Bacillus thuringiensis subsp. israelensis HD567 “code 4Q1”, and commercial product “Skeetal”. One hundred percent mortality was observed against neonate larvae after 7 days of application by Bt 13.4 toxin. Third instar larvae were very susceptible to Bt A7 and Bt M-Ag 21.6 strains with 68% mortality (Lethal Concentration: LC50 = 1.115) at a dose of 150 μL/g. The Bt A7 strain was also highly toxic to adults with 81.66% of mortality after 7 days of application. This study demonstrated that some of our collection Bt strains can contribute to integrated C. capitata management system with strong biological control components.

Immunologic thrombocytopenia (ITP) is an autoimmune disease associated with the production of autoantibodies against specific platelet membrane glycoproteins. A thrombotic event as an unusual occurrence during ITP is becoming more and more frequent. In fact, several recent studies have shown an increased thrombotic risk in this situation. The case presented here is that of a fifty-one-year-old woman with extensive cerebral venous thrombosis 2 years after her ITP diagnosis. During IT, thrombosis may be triggered by the release of pro-thrombotic platelet micro-particles and by platelet activation due to the interaction between autoantibodies and platelet glycoproteins. Immunosuppressive therapy has also been linked in several studies to the thrombotic phenomenon. Increased thromboembolic risk should be taken into account in all ITP patients.

FlexRay is a vehicular communication protocol designed to meet growing requirements in hard real time automotive systems and to support time triggered as well as event triggered paradigms. Thus, there has been a lot of recent interest in timing analysis techniques in order to provide bounds for the message communication times on FlexRay. In this paper, we present an approach to compute the WCRT （worst case response time） for periodic and sporadic tasks, within a FlexRay node, responsible for sending messages on the FlexRay SS （static segment） and DS （dynamic segment）. On the other hand, we propose a scheduling table for messages transmitted over the FlexRay SS. An interesting innovation would be the use of a scheduling algorithm performed on a FlexRay node to guarantee the arrival of the right data on the right time and to ensure that every task meets its deadline. As application, we will use the extended SAE （society of automotive engineers） benchmark for the FlexRay network to identify the static and dynamic tasks, and calculate the response time, based on a hybrid scheduling model to further prove that the deadline of the SAE benchmark applications is insured.

Background: Common clinical manifestations of cytomegalovirus (CMV) infection include flu-like symptoms with fever, diarrhea, leukopenia, and elevated liver enzymes. Diagnosis is made by detection of the virus by buffy-coat blood culture or by polymerase chain reaction (PCR) analysis. Methods: Here we describe a women renal transplant recipient who presented with acalculous cholecystitis with CMV viremia, anemia and leucopenia tree months after she received a kidney from cadaveric donor. Results: Retrospective analysis of peripheral blood by PCR analysis was positive for CMV DNA. Treatement with Intravenous Ganciclovir was started after diagnosis. The role of cholecystectomy in patients diagnosed as having acalculous cholecystitis associated with systemic CMV disease remains unclear. Conclusions: Because CMV infection is common in transplant patients, the atypical manifestations of CMV should be considered in the differential diagnosis of posttransplant complications. Detection of CMV DNA in the peripheral blood by PCR analysis may help identify these patients.

Excess or lack of levels of nitrate in drinking water is harmful to the human health, the concentration of NO-3 ions must be maintained at 50 mg/l. Donnan dialysis (DD) used as a driving force of the concentration gradient is an effective and simple technique for nitrate removal. In this paper, the transport of nitrate through an AMX anion-exchange membrane has been studied as a function of driving ion nature, receiver phase concentration, flow rate, temperature and agitation rate under Donnan dialysis condition. It was observed that the hydrodynamic conditions and temperature were the main variables affecting the transmembrane flow. As the driving ion, the chloride ion is more efficient than the hydrogeneocarbonate ion. The systematic study of the different parameters involved showed that the nitrate removal efficiency obtained with a feed synthetic nitrate solution (62 ppm) was off 96%. This efficiency slightly decreases for a tap water containing the same nitrate concentration;it was about 84%. This can be attributed to the complex ionic composition of the natural water.
